Alienware 17 r3 laptop, internal speakers work fine, headphone jack(s) seem to be ignored, so I can't get sound to an external speaker. (The Alienware has a second "microphone" jack, which apparently can double as another headphone jack.) Also: I've got it dual-booted to Windows 10, and the headphones work fine under Windows.
I saw that another user had essentially the same problem Ubuntu 15.10 Headphones No Sound but it doesn't seem to have been resolved. My system shows only small variations from the original bug report, so it's surely the same issue.

Everything works fine with internal, built-in speakers. But I can't get any sound out of the headphones. Anyone have any ideas? Thanks!
Edit
In case it helps anyone, Windows 10 lists the sound card as "Sound Blaster Recon3Di" (where the headphones work just fine).
